Usability Evaluation of the Novel Smartphone Application, HPV Vaccine: Same Way, Same Day, Among Pediatric Residents

Objective: Scalable, deliberate practice training strategies to administer evidence-based recommendations are necessary to improve human papillomavirus (HPV) vaccination rates. We sought to characterize resident clinicians' perceptions regarding the usability of the HPV Vaccine: Same Way, Same Day smartphone application (app). Usability, a critical aspect of digital programs to promote behavior change, was evaluated.

Methods: Fifteen third-year pediatric residents were recruited to complete a usability evaluation of the HPV Vaccine: Same Way, Same Day app, which includes simulated role-play scenarios in which users interact, as a pediatrician avatar, with an animated parent hesitant to accept the vaccine for her child. The app provides information about the vaccine and utilizes deliberate practice, a purposeful and systematic approach to improve performance, to teach evidence-based vaccine recommendation practices, including motivational interviewing skills. Data were derived from in-depth, semistructured interviews with pediatric residents. We used a constructivist general inductive approach to illuminate perspectives via inductive coding and pattern identification. Garrison's theoretical construct on self-directed learning was used to cluster themes into conceptual categories.

Results: We classified interview data in 3 conceptual categories: self-management, internal monitoring and motivational principles. Residents described the app as interactive, easy to use, succinct, informative, engaging, and practical. All residents would recommend the HPV Vaccine: Same Way, Same Day app to a colleague. Residents suggested adding more complex cases for future iterations.

Conclusions: From their perspective, pediatric residents reported that an app using deliberate practice principles has the potential to inform and advance providers' counseling skills regarding the HPV vaccine.
